CAMERA.

SPECIFICATION forming part of Letters Patent No. 780,590, dated January24, 1905.

Application led July l2, 1902. Renewed May 21, 1904. Serial No. 209,046.

To (1J/Z whom, it may concern:

Be it known that I, JOHN N. ANDERSON, a citizen of the United States,and a resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Cameras, of which thefollowing is a specification, and which are illustrated in theaccompanying drawings,forming a part thereof.

This invention relates particularly to that type of camera which is usedfor enlarging; and its object is to provide a construction of camerawhich, while capable of use for this purpose, may be readily transformedinto a taking-camera for studio-work; and a further objeet is thegeneral improvement in this style of instruments.

The usual practice in enlarging photographs is to do' it by means of anelaborate outlit, which involves the use of an entire room. Thenartificial light is used, the lamp or lantern is usually placed on theoutside of the room and an aperture provided in the wall, within whichthere is fitted the condensinglens, and an easel or some form of supportis set up within the room and independent of the other parts of thecamera. This practice of course involves a considerable investment ofcapital,l and as a consequence the ordinary photographers studio is .notequipped with an enlarging apparatus, and whenthe photographer receivesan order for portrait-photographs including pictures of varying sizes hemust either make a plurality of negatives or send his negative away toan enlarging-studio, and this latter course he must always take if hisorder is for a picture of any considerable size.

One of the objects, therefore, ofthe present invention is to enable aphotographer to provide himself, without material increase ofinvestment, with a studio-camera which will enable him to both i takeand enlarge. After the sitting,'by which he secures a single negativefrom which he will directly print the photographs of ordinary size, hemay remove his camera to his dark room and in a very short timetransform it into an enlarging instrument and after developing hisnegative simply mount it in the negative-holder of the camera and atonce print a large picture from it, which may be immediately developedto mount and iinish for delivery.

A further advantage in my improved instrument is that the camera andframe for supporting the sensitive paper used in enlarging work aremounted together on a single frame and made adjustable for the purposeof determining the degree of enlargement and securing the focus withoutdisturbing the alinement.

The invention consists in the construction hereinafter fully describedand which is illustrated in the accompanying drawings, in which- Figurel is a side elevation of the camera with its frame extended. Fig. 2 is aside elevation of the same with the frame folded. Fig. 3 is a centrallongitudinal section of the camera, only a portion of the frame beingshown. Fig. Il is a detail sectional view of the frame to which the lampis attached. Figs. 5 and 6 are detail sectional views of twocamera-sections. Fig. 7 is a plan view of the camera with its frameextended, some portions of the latter being broken away. Fig. 8 is aface view of the holder carrying the negative to be enlarged. Fig. 9 isan edge view of the same member. Fig. I0 is a side elevation of theadjustable support for holding the sensitized material. Fig. Il is aside elevation of the camera arranged for primary work. Fig. 12 is afront elevation thereof. Fig. I3 is a rear elevation of the same. Fig.ILL relates to a detail of the hinged frame, and Fig. l5 is a section onthe line l5 of Fig. ll.

A bed-frame l5, comprising an inner rectangular frame I6 and an outerframe 17, having guide-strips in the side bars thereof enteringguide-grooves in the side bars of the frame 16, so that the frame I7 mayslide longitudinally of and on the frame 16, and a central longitudinaltrack member I8, tixed to the frame l5, carries the camera, which iscomposed of the box-like sections 19, 20, and 2l. Threecondensing-lenses 2.2, 23, and 24C are preferably used and carried byremovable holders mounted in the camera-section 19, although the numberis not material and their arrangementmay be other than that described.

IOO

The condensing-lenses are plano-convex in form, and two 0f them, as 2223, may be disposed with their convex faces adjacent or toward eachother, the third one, 24, having its convex face directed toward theother two. One end of the bellows 25 is secured to the section 2O andthe other end to the section 21, and the latter being' the front sectioncarries the lens-tube 26.

The sections 19 and 21 are independently movable, the sec-tion 19 beingIslidable and removably mounted on the side rails of the outer frame 17,while the section 21 is mounted 0n a base 27, sliding on the side railsof the inner frame 16 and held in engagement therewith by a T-clamp 28.attached to the said base and running in a correspondingly-shapedchannel in the track 18.

Any suitable lamp, such as the arclamp 29, is used and is inclosedwithin an opaque casing or lantern 30, having a front frame 31, by meansof which it is secured to the rearward end of the camera, any suitablemeans, such as the hooks 32, projecting from the frame 31, beingprovided for holding the said frame against the section 19. Instead ofan arclamp any other suitable lighting agent, as an acetylene-gas lamp,may be employed.

A slide 33, carrying a ground-glass screen 34, is preferably mountedwithin the frame 31, so as to soften the light from the lamp, and asimilar slide, 35, provided with a ruby glass 36 to be employed when itis desired to light the dark room, may also be mounted in the frame 31.

A frame 37 is provided for carrying the support 38, upon which thesensitized material is carried for receiving the enlarged image. Theframe 37 is oblong rectangular and is attached to the base 15 by meansof an intermediate frame 39, fixed, as at 40, to the frame 37, andhinged, as shown at 41, to the base 15. The length of the frame 39 isthe same as the height 0f the camera, so that when the support 38 isremoved from the frame 37 the latter may be folded over upon the top ofthe camera, as shown in Fig. 2.

A leg 42 is hinged to the outer end of the frame 37, so that it may foldagainst the latter, as shown in Fig. 2, and may be extended to rest uponthe floor and support the frame when the latter is in service. lt willbe understood that the base 15 is adapted te rest upon a suitablesupporterstandard. (Not shown.)

The frame 37 is provided with a longitudinal track 43, in alinement withthe track 18, and the su pport 38 is removably and 4slidingly engagedwith this track by means of a T- clamp 44. r1`his support comprises astandard 45, a vertically-adjustable plate 46, in engagement therewithand provided with a lockingclamp 47, and a transversely-sliding plate48, in engagement with the plate 46 and adapted t0 receive thesensitized material, which is secured thereto by means of spring-lingers49.

rIhe negative-holder frame 50 enters laterally within the camera-section20, seating itself in a chamber 51 therein, and is in the form of arectangular frame carrying a plate 52. This plate is centrally aperturedto rcceive a disk 53, which may be oscillated by means of a handpiece orstem 54 projecting through a suitable slot in the frame 50, the saiddisk being centrally apertured to receive the negative-carrier 55, whichis secured in place by the spring-lingers 56.

By means of the various adjustments provided as hereinbefore describedthe camera is conveniently extended or contracted for focusing purposes.The negative may be adjusted accurately with reference t0 the lens. Thesupport 38 is always true with reference to the camera and is guided inits movement to and from the lens strictly in line therewith, and theplate carrying the sensitized material may be readily adjusted in alldirections.

The mechanism shown for adjusting the lens-tube in order to secure alineadjustment, and consisting' of the hand-lever 57, anchored to theT-clamp 28 and connected by a link 58 to the sliding base 27 of thesection 21, and the pivoted levers 59, connected by links 60 to theoscillatable frame 61, carrying the lens-tube plate 62, need not bedescribed in detail, as they are well known in the art and form no partof my invention.

l/Vhen the camera is not in use, the sliding' frame 17 may be telescoped0r pushed in on the frame 16, thereby moving the camerasections and lampinto the compact form shown in Fig. 2, and the support 38 having beenremoved from the frame 37 the latter may be folded over to the top ofthe camera, and the whole takes up but very little space and may beconveniently packed for shipment.

It not infrequently happens that because of lack of room or foreconomical reasons a photographic studio is not provided with anenlarging-camera, and for that reason it becomes necessary for theartist to employ others to do such enlarging as he may receive ordersfor.

One of the purposes o1' the present invention is to provide a camerawhich may be readily reorganized for use either as a primary or takingcamera or as an enlarging'- eamera. lts form for the latter use hasalready been described. To adapt it for primary use, the lantern 30 isremoved, the condensing-lens section 19 taken away, the negative-holder50 is withdrawn, and the aperture for receiving it is closed by a strip63. The plate 62, carrying the lens-tube, is removed from theoscillatable frame 61 of the camerasection 21, and it is inserted in theol'iening 64 of the camera-section 20, and a frame 65, carrying' afocusing-screen 66 and adapted to receive the plate-holder in the usualmanner, is secured to the front of the camera-section 21,

IOO

engaging pins in the projecting foot-piece 67 of the section 21 andbeing secured at the top by spring-clamps 68. When thus organized, thecamera is reversed from its previous form. The hinges 4l are preferablyof such form that their two leaves are easily disconnected, so that theframe for carrying' the support 36 may be quickly removed and be out ofthe way of the operator when using the camera for taking purposes.

In order to insert and remove the middle condensing-lens 23, the openingfor the holder of one of the outer lenses, as 22, is made larger thanthe middle-lens holder, so that the latter may readily be passed throughthe said opening.

I claim as my inventionl. A photographic camera having its lenscarrierreversible from end to end of the camera.
